Be it known that I, 'JAMES MONTGOMERY, of the city, county, and State of New York, have invented anew and improved Appara! tus for Corrugating Sheet Metal, 0f which the following is a specification.

lily machinery is so constructed and arranged that the iron to he corrugated is laid upon a carriage having at the edge next the operator a raised iiange or stop, against which the rear edge of the sheet to be corrugated is placed and held by the gripping-bar. The carriage is pushed forward to enter the front edge of the sheet between thelongitudinally-fluted rolls; 'but in orderto insure the gripping of the sheet at its extreme edge, so that the edges of different' sheets will come to the same part of the corrugation, and thus adapt them to fit together, I employT a stop adjustable for different'widths of .iron and serving to limit the forward movement of the carriage. To change the machine for a new width of iron, the stop is carefully adj usted for the first sheet by means of a suitable setting-screw, after which it will operate with great rapidity and perfect accuracy on successive sheets of uniform width. In some cases I propose to employ, instead of a stop -which may limit the advance of the table to apoint where the corrugated rolls can grasp the extreme edge of the plate, asabove set forth, a' temporary stop, which will prevent the table, advancing quite so far, and, certain period in the revolution of the rolls, will insure accurate uniformity in the introduction or feed of the sheets.

In the accompanying drawings, Figurel reprcsentsthe apparatus in elevation. represents vatransverse scotion thereof.

A B is 'a pair ofrolls, made hollow in order to'combine lightness with strength, and for the purpose of passing th rough them water or air to vkeep them cool when the metal is rolled hot, as

in the 'ease ofboiler-plate. These rolls may be driven bya band-wheel, C, in customary manandare formed on their peripheries with corresponding and lintermeshing longitudinal Y -for the purpose of corru- ,flaltingv sheet -metal which is .passed between ein.

l D D. are the customary adj ustingscrcws to regulate the proximity of the rolls. E is a shelf or table for the reception of hundles of iron sheets in convenient position for them to be taken one by one.

F is carriage for feeding the sheets to the rolls. At the rear edge of the sa' l mage is a flange, G, against which. the re, 1 edges of the sheets rest and clamp, H.

I is a'stop to limit the forward. movement of the table, and itself adjustable by a screwrod, J, operated by a crank, K. l y L is a chute to receive and conduct the corrugated sheets from the rolls.

- Instead of the stop I, I may employ an automatic stopping and releasing device, consisting of a sliding catch, M, projecting downward in front of the carriagel and retracted at .proper periods hy cams on the u' le' ell, A, acting on a lever, N, to the free e.. ei which the catch M is pivoted.

0 O 0 represent various parte the framey Operation: A bundle of metal sheets of uni form width being unbound and laid upon theI table E, the operator draws the upper sheetv onto the carriage F with its rear edge resting against the iiange G. He then grips this edge firmly with the clamp H. The action presses the edge more firmly against the ilange. The carriage F is then moved slowly forward, the stop I being by means of the screw-rod J and crank K moved gradually forward in front of the carriage to allow the advance of the latter. This slot." movement is continued until the extreme forward edge of the sheet is caught by the rolls A. B, which draw the sheet from the carriage, and at the same instant' the operator ceases to moveV the stop l, which thus forms a gage to limit the forward movement of the carriage to a peint where it will permit the front edge ofthe sheet to be seized by the rolls.

been thus adjusted,

the operator can. then feed successive sheets of uniform width with great rapidity", and the eorrugations et' the various sheets will precisely correspond, because the rst grip of the rolls is at the extreme edge of each sheet.

if preferred, a sliding catch, lli, may be em'- vployed to stop the carriage F at a point just where they are held by a The stop havingA short of where it would permit the grippingof y the sheet. In this ease the seid catch, bein` withdrawn automatically by the lever N, actu- 4of the corrugntions thereon being` se arranged that en accurate number el.' corrugutions will be produced en euch shcei und. the two edges of each sheet being :it correspoiuling paris el the corrugations the sheet will be reversible.
